How to unclog a dishwasher

Step 1: Find out why your dishwasher is clogged

Your dishwasher can become clogged for a variety of reasons. The most common problem with a clogged dishwasher is that the dishwasher drain gets clogged because there is too much food residue stuck in it. Also, if there is a kink in the drain hose, your dishwater cannot drain properly.

In both cases, a cloudy residue of water will remain in your dishwasher. After a while, this will start to smell and that is definitely not pleasant in the kitchen!

So for the first step, you need to check both the filter and the drain hose and clean them properly. First, hold the filter under running water for a while and when all the dirt has been rinsed off, place it in a bowl of boiling hot water. Sprinkle baking soda in the water when it has cooled down a bit and after 15 minutes you can take the filter out again. You should rinse the filter well before putting it back in.

 

Step 2: Cleaning the clogged dishwasher filter

So for the first step, you need to clean the clogged filter properly. First, hold the filter under running water for a while and when all the dirt has been rinsed off, place it in a bowl of boiling hot water. Sprinkle soda into the water when it has cooled down a bit and after 15 minutes you can take the filter out again. You should rinse the filter well before putting it back in.

Step 3: Cleaning the clogged drain tube

If the clog is in the drain hose of your dishwasher, you need to loosen it first. This works differently for every dishwasher, so always check your owner’s manual.

To find out if you are dealing with a clogged drain, take a long object. Move this through the hose and see if you find any blockages. In most cases you can pull these blockages out with the long object, otherwise you can pour boiling water with baking soda and vinegar into the dishwasher, which will loosen these blockages and flush them out.

 

Step 4: Cleaning the clogged drain pump

When there are too many food particles in your drain pump, your dishwasher can also become clogged. Before removing this part, you should also refer to the instruction manual, otherwise you risk damaging your drain dishwasher.

Also, keep in mind that the drain pump can be clogged with anything and you can’t see it right away. So put on safety gloves just to be sure, there can be pieces of glass in the drain hose in addition to food residue.

You then clean the drain pump thoroughly with boiling water to remove even the most stubborn food residue. You can use a mild detergent for this, but you’ll need to rinse it well afterwards.

Step 5: Unclogging your sink

A problem with a clogged dishwasher doesn’t always have to be in the appliance itself; your sink can also be clogged, preventing the water from your dishwasher from draining properly.

To unclog your sink, sprinkle some baking soda in the sink, which you rinse away with boiling water after five minutes. If all goes well, this will loosen and dissolve the clog.

 

Step 6: Check that your dishwasher is working properly again

To make sure the problem is fixed, turn on your dishwasher. Do not do this if there is still a layer of water in the machine. This is because you run the risk of too much water entering the machine, which will cause a leak.

Step 7: Prevent your dishwasher from clogging up

You can also prevent a clog instead of fixing it, here we have collected a few useful tips. As mentioned earlier, the most common cause of a clogged dishwasher is that the filter and drain hose become clogged. You can prevent this by always rinsing your dishes before putting them in the dishwasher. You’ll rinse away the worst of the food residue, preventing it from sticking.

Also, always use the right dishwasher tablets. These can clean your machine on the inside, so you won’t have any limescale problems. All the water can then be drained away.

You can also fix blockages by cleaning your dishwasher regularly. Wipe down the spray arms regularly with a cloth, clean the inside of the dishwasher, and regularly flush boiling water down the drain line.
